● When move control "EN" = 1 or "EN↑" ( P instruction) transition from 0 to 1, the contents of the source
register Rs will be written onto the register Tdpr indicated by the pointer Pr within the destination table Td
(length is L). Before executing, this instruction will first check the pointer clear "CLR" input signal. If "CLR" is
1, it will first clear the pointer Pr, and then carry out the move operation. After the move has been completed,
it will then check the Pr value. If the Pr value has already reached L-1 (point to the last register in the table)
then it will only set the move-to-end flag "END" to 1, and finish execution of this instruction. If the Pr value is
less than L-1, then it must again check the pointer increment "INC" input signal. If "INC" is 1, then Pr value
will be also increased. Besides, pointer clear "CLR" is able to operate independently, without being
influenced by other input.
● The effective range of the pointer is 0 to L-1. Beyond this range, the pointer error "ERR" will be set to 1, and
this instruction will not be performed.

z The example at left at the very beginning pointer Pr = 4,
the entire content of table Td is 0, and the Rs value is
8888. The diagram below shows the operation results
when X1 have the transition of 0→1 twice.
z Because INC is 1, Pr will increase by 1 each time the
instruction is executed.
